Sidi Rex
The Sidi Rex is a no-compromise sport and race boot built around a high abrasion resistance microfiber upper reinforced by an external fiberglass protective structure and fiberglass nylon exoskeleton. A high-density resin dial closure — adjustable from either side — delivers a precise, repeatable fit, while replaceable shin plates, ankle support braces, an asymmetric heel cup, and a replaceable slider protect and extend the life of the boot session after session.
